What is blue and white jade?

Blue and white jade is black and white jade in Hetian jade. The color of common jade species in Xinjiang is darker than that of dot ink and gather ink.

In the traditional sense, jet refers to white jade and sapphire infiltrated by graphite. As jet, of course, the better, but it must be jade, otherwise it is stone. Jet is mostly gray, neither black nor white. This material is called "blue and white". Generally speaking, the "blue and white" jade is quite delicate, with a good sense of fat, and it has a unique feeling when used. Among them, black and white "blue and white" is blue and white.

The correct classification of traditional jet is divided into dot ink, aggregate ink and full ink according to the form of graphite entering water. As the name implies, spotting refers to the point distribution of graphite, and gathering refers to the fact that graphite is relatively dense, but it does not fill all the original jade species, and its appearance is dark gray. Full ink means that graphite occupies every space of the original jade species and is very dense. The "black as paint" in all inks is the top grade, which is very rare.
